Connecting loudspeakers
If your source provides bass management, you can use the BM9S LFE input alone in
LFE or SLAVE mode, depending on the management system capabilities. Avoid
double processing if possible.
Connecting speakers
1. Connect the subwoofer as explained in “Connecting a single subwoofer” on
page 7.
2. From the Subwoofer SAT/SUB OUT connect a XLR cable to the inputs of the
power amplifier you use for your speakers.
Operation Switching the subwoofer on/off (POWER ON/OFF)
Once you have ensured yourself that all necessary connections have been made, the
subwoofer and the connected components can be switched on.
X Switch the subwoofer ON with the main POWER switch on the rear panel.
The status LED on the rear of the subwoofer will light up red.
Automatic mode
After switching on the BM9S is in automatic mode:
• When a music signal is detected, the internal amplifier is activated automatically.
The status LED on the back of the subwoofer will light up green.
As long as a music signal is available on the subwoofer’s input, it will remain
switched on.
• After 15 to 20 minutes of not sensing any input music signal, the subwoofer will
switch itself to Standby mode automatically.
The status LED on the back of the subwoofer will light up red
Note:
• The signals connected to the inputs are provided at the Slave OUT for connecting
another subwoofer. See page 7 to learn more about connecting multiple
subwoofers.

Adjusting the volume (Gain)
Operation
Dynaudio Acoustics BM9S 9
Adjusting the volume (Gain)
The correct volume setting is an important aspect in achieving a well balanced
speaker combination.
X Adjust the Gain control, until correct setting is reached.
Selecting the subwoofer cut-off frequency
(SUB Lowpass)
The SUB Lowpass control allows the frequency range of the subwoofer to be
defined. Above the selected frequency the sound level decreases rapidly. The correct
setting of this cut-off frequency is important for a well balanced combination of
subwoofer and speakers.
Selecting the cut-off frequency
X Set the SUB Lowpass control to the desired frequency between 50 and 150 Hz.
Please also heed the instructions given in the operating manual of your loudspeakers.
CAUTION
HIGH SOUND LEVELS!
X To avoid auditory defects do not listen to high sound levels
over a longer period of time.
Note:
• You cannot adjust the volume, when subwoofer is in slave mode. In this case the
volume is controlled by the setting of the master subwoofer.
Note:
• The SUB Lowpass only works on SAT/SUB input.
• Perhaps subwoofer cut-off frequency is already set in the bass management of
your source. Please refer to the operating manual of your source. In general use
only one bass management system.
